Geometric effects resulting from square and circular confinements for a particle constrained to a space curve
Yong-Long Wang, Meng-Yun Lai, Fan Wang +2
Investigating the geometric effects resulting from the detailed behaviors of the confining potential, we consider square and circular confinements to constrain a particle to a spac…
Gauge invariance, Lorentz covariance and canonical quantization in nucleon structure studies
Fan Wang, X. S. Chen, W. M. Sun +2
There are different operators of quark and gluon momenta, orbital angular momenta, and gluon spin in the nucleon structure study. The precise meaning of these operators are studied…
Problems related to gauge invariance and momentum, spin decomposition in nucleon structure study
Fan Wang, W. M. Sun, X. S. Chen +1
How do the quark and gluon share the nucleon momentum? How does the nucleon spin distribute among its constituents? What means the quark and gluon momentum, spin and orbital angula…
New application of decomposition of U(1) gauge potential:Aharonov-Bohm effect and Anderson-Higgs mechanism
Jian-Feng Li, Yu Jiang, Wei-Min Sun +2
In this paper we study the Aharonov-Bohm (A-B) effect and Anderson-Higgs mechanism in Ginzburg-Landau model of superconductors from the perspective of the decomposition of U(1) gau…
Art of spin decomposition
Xiang-Song Chen, Wei-Min Sun, Fan Wang +1
We analyze the problem of spin decomposition for an interacting system from a natural perspective of constructing angular momentum eigenstates. We split, from the total angular mom…
Proper identification of the gluon spin
Xiang-Song Chen, Wei-Min Sun, Fan Wang +1
Properties of the recently proposed gauge-invariant gluon spin are studied and compared to the usually defined "gluon polarization" . By explicit 1-loop calculations in a…
